How to remove the extra vertical line at the right in some menu bars?

[mvlcek]

In the themes Emporium and Woodlands there is an extra vertical line at the right in the menu bar.

Can that line be removed in a simple way?

Don't know about the theme, but normally you would define the line as left border of all but the first <li>, like:

Code:

ul.sitemenu li + li { border-left: 1px solid black }
